Specification of Letters Patent. Patented Sept. 20, 1921 Application filed February 21, 1920. serial No. 360,362.

To a-ZZw/lom it may concern:

lie it known that l, ARTHUR l PooLn, a citizen of the United States, residing at Kcnilworth, in the county of Cook and State of l llinois, have invented certain new and useful Improvements in Locks for Totalizers, oi? which the following is a specific tioni My invention is an improvement in typewriter computing, machines and is especially applicable to the lvahl adding machine now extensively marketed by the Remington llypewriter Company, and which is thoroughly described in the issued patent to John (I, llahl, No. 1,270,441, dated June 19l8 The object of my invention is'to provide a loclr for the totalizer of a machine'of the above type, to the end thataccident-almisoperation of the totalizer may be prevented.

llefmcnce to the cited patent to lVahl, particularly to Figures 14 and 16 thereof, will disclose that the totalizer described in. said patent consists of a series of gear wheels adapted. to be actuated .s-cr'iatim by a master wheel.

In order to provide for the operation or carrying or accumulating: of tens, each gear wheel is connected to a similar gear wheel of next higher order by at Geneva gear,

which has the function of advancing the wheel of higher order one step for each complete cycle of the wheel of lower order. In thclVahl machine described in the cited patent, this cycle consists of ten steps.

in order to prevent overthrow. these intermediate rears in the l'l ahl machine are in the well known Geneva form, which includessuitable locking),- surfaces. to the end that the wheel of higher order is locked against rotation except at the time when motion is communicated to it by a carrying: step from the wheel of lower order, and for the further purpose of insuring that but one step shall be made by the wheel of higher order at this time' 1 As so far described, the lVahl totalizer contains a chain: of gear wheels which can be actuated only at the lowest wheel, since all the wheels of higher order are locked except as they may be unlocked to be ad vanced during'acarrying operation,

In order to provide for the insertion of numbers at various decimal places, the intermediate whcels of the lVahl totalizer just referred to are mounted on certain swinging arms, which are adapted to be raised before a wheel is operated. Raising of these intermediate gears thus unlocks the chain of gears at the actuated point and there remains a locked chain of gearing from the actuated pointto the highest wheel of the totalizer, thus effectually preventing any overthrow in said higher wheels.

The swinging arms upon which the intermediate wheels are mounted are held in their normal position by spring pressure, and if force were applied to any wheel of the totalizer, then it is possible to rotate such a wheel, due to the fact that the intermediate gears are forced out of mesh with their associated wheel, due to the yielding of the spring which serves to hold the swinging arm in its normal position.

It is the object of my present invention to provide a lock, such that when the'totalizer is out of the adding zone, that is, is out of a position to be actuated by-the master wheel of the machine, the above described accidental rotation will be impossible.

My invention may be best understood by reference to the accompanying drawings, of

Fig. l-is a sectional view of the totalizer including the locking mechanism peculiar to my invention,

Fig. 2 is a top view of the same, and v Fig. 3 is a perspective view of certain details to be described hereafter.

While I haye described my invention in its preferrcdform as adapted to a \Vahl -tains in each decimal place a carrying- Wheel 10, which is rotatably mounted on'ashaft 11, held between the totalizer side plates 12 and 13. nected by the transfer wheel 14- to the carry- Each carrying wheel is con mg wheel 10 ofnext higher order. Transfor .vhcols are rotatably iounted on the. swinging arms rotatablv mounted on shafts l6 and 17 extending between the Quic plates 12 and 13 of the totalizer. Each of the swinging arms 15 provided with an o 'iorating cam 18, which opcratcs on a safety bar 19 rot-atably inountctl between the side. plates 12 and 13 on a shaft 2!). Zach one if the swinging arms is provided with a locking surface 21 mam-.96, to be engaged by a ooncci'itric cam surface 2:2 on the safety bar 19 which extends across the entire width of the totalizer and is adapted to engage any of the swinging arms 15. Upon any of the swinging arms 1.5 being actuated, tho cam 18- will lift the safety bar 19, rotating it on its shaft 90, and. the concentric surface 22 will engage the cams 21 on all oi? the balance of the swinging; arms 15, thus preventing said arms from being raised out of mesh during the subsequent actuation of the gear Wheels 10. This safety bar action has been very thoron hly described in the issued patont to Wanl and Goldberg, No. 896,871, dated August 1 35, 1908.

lhc object of the safety bar arrangen'icnt just described i=- to lock all the swinging arn1s 'l5 in their position, except the ono, which has been raised to permit the actuzition oi"; the totalizcr. It is obvious that then safcty bar l9-Wil1 not prevent the simultaneous raising, of more than one of the swinging arms 15, and it is this fact which permits one to rotate the. wheels 10 when the totalizcr is out of the adding zone.

All the mechanism just described is com rnon to the totalizcr described in the Wahl Patent No. 1.270.471. I will now describe the mechanism peculiar to my present invention lirotally mounted on the side plates l2 and 13 ot' the totalizer a bail 23, one arm 24' of which is adapted to rotate on a stud screw in the side plate. 1.3. The other arm 26 of the bail is provided with a square hole QT (Fig. 3 adapted to fit over a square till on a stud 29 rotatably mounted in tho :eiido plate 12. A screw 30 scrvcs to hold the arm 21C- on ts scat 25% on the stud 2!). Rigid with the stud 99 is an arm 31 whi h extends on the inaidc oi toe totalizer and is held in enw'ugqn'icnt with thesafoty bar 15) by a spring: 32 extending between the arm 31 and a stud 3% in the side plate 12. Thus the bail 1 will tend to rotate in a clockwisodircction (Fig. l) and thus rotate the safety has: 19 thereby bringing the concentric surlaigi ina position to lock the cams 9L thus prevcnting: any of the swinging" arms 1:: from being raised. lilu-n the part; are n the, above described condition. the totali'la-r a: a wholo is locked. sinco thowhccl 11)- of lowcnl. ordov is lociictl by the units l -l{ 34. which is rnountcd on an arm similar to the swinging arms 15 and all the wheels of higher ordcr arc lockcd becauso ol the prescncc oi the (leneva gears. 14. When the totalizcl' is in this condition it is impo. sible to rotate any of the wheels. either by accident or dcsigu.

To provide for the. unlocking" of the totalizcr whcn thc sauic (MINUS into an operating Zone. that is to say. when any of the wheels l0 arc in engagcnicnt with a music! wheel 37 which serves to insert numbers into the totalizer in the method described in the cited patcnt to Wald. the bail 2 comes into operative cngagcmcnt with a roller 36 mounted on the framework 7 ol thc adding machine. clined surfaccs 3n and and a straight surface 4-1 The inclined surfaces 38 and ill) atlord an cngragenicnt with the roller an. and thc straight surface ll) serves to maintain the bail 23 in an in ulcrativc posi tion. that is. it serves to maintain the bail in the position shown in Fig. 1 during the entire adding zone of-thc totalizcr. When the roller an is engagicd with the straight surlace h) of the bail 23, the normal opt-rm tions of the totalizer are not interteri-zd with. since the arm 31 is in the. position shown in Fig. 1. l'lowever, as soon 21 the totalizer passes out of the adding zone. the bail 23 t'alls to a lower position, due to the action of the: spring 32. thus rotatin; the salcty bar 1.) and locking all of the swinging arms. including, the one carr viiug" the units lock :54 in the position shown in Fig". 1. As pointed out. when the arms 15 arc hcld or lock d in the position shown in Fig. 1. it is impossible to rotatev any of the \vhcels of thc totalizcr. and since the numbcr wheels are geared to the wheels 10. the totalizer is completely locked. Since the number whccls M of the totalizer are gcared to the wheels 10. it is impossible to.inscrt any number whatever into the totaliscer. I v 2 From the above it will be apparent that whcn a totalizer is out of thc adding zone. all of thc wheels will be locked and it will be impossible to li'lHl'l] a number therein by ac cidcnt. However. as soon as the totalizcr enters thc actuating zone. the engiujcinent of thc bail 23 with the roller 3U will, by bringinn the arm 31 to the position shown in Fig. I. disable thc lock.

It is apparent that the provision of this lock on the totalizcr ot' the \Vahl machine is entirely optional; that they will operate very well without the lock forming thc subject of my present invention. but that this l()('l( will aftord an additional safe-guard against the totalizer being :uxridcntally disturbed during thc time when it is not in the operating zone. 8

"Many iimirovcincuts and varizuiiona may be made from the hcrcin deF cribed mechanism witlunit departing" irom thc spirit of my invcnt-ion. uinco I claim:
